Ohmic Resistor. Therefore in a circuit if a resistor s resistance is equal to voltage divided by current the resistor is ohmic. In an ohmic resistor the resistance provided is the same regardless of the type of current that passes through the device.
An element resistor or conductor that behaves according to ohm s law over some operating range is referred to as an ohmic device or an ohmic resistor because ohm s law and a single value for the resistance suffice to describe the behavior of the device over that range. The designation of ohmic versus non ohmic involves an electrical law known as ohm s law which was developed by georg ohm. A resistor that functions according to ohm s law is called an ohmic resistor.
When current passes through an ohmic resistor the voltage drop across the terminals is proportionally to the magnitude of resistance.
Ohm s law essentially says that current is equal to voltage divided by resistance. Ohm s law essentially says that current is equal to voltage divided by resistance. As a result a chip resistor may have a significant voltage coefficient of resistance i e the resistance may vary with the applied voltage. High ohmic valued chip resistors exhibit characteristics of both insulators and normal resistors.
